Englewood Cliffs, N.J. -

LG Electronics

filed patent-infringement claims with the

International Trade Commission (ITC)

LG also reportedly filed similar civil suits against Sony in federal court in California, looking for cash compensation.

The moves follow similar actions

Sony has also targeted LG Blu-ray Disc players in a separate civil lawsuit.

In its complaint with the ITC against Sony, LG said Bravia LCD TVs infringe four LG patents relating to how the sets receive and process digital TV signals. It also claimed that the PlayStation3 gaming console, which employs a Blu-ray Disc drive, infringe four patents LG holds on various technologies used in Blu-ray Disc players.

The Blu-ray patent complaint covers technology for processing multiple data streams, and for reproducing data stored on read-only devices.

Meanwhile, the LG phones named in Sony's patent claims include the Lotus Elite, Neon, Remarq, Rumor 2 and Xenon.
